WARMING APPARATUS.

Specification of Letters Patent No. 29,364, dated July 31, 1.860.

To all whom 'it may concern:

Be it known that I, JosnPH H. Davis, of IVobui-n, in the county of Middlesex and State of Massachusetts, have invented cer'- tain new and useful improvements in chimney-flues andradiators for warming apartments, whereby much of the heat usually lost. by the use of stoves, ranges, furnaces, grates, or open lires may be saved by using a series of flues and radiators so divided by diagonal, horizontal, fixed, swinging, and vertical partitions and valves, to be moved by rods or shackle-jointed levers or their equivalents, as to form when the combined arrangement is in use a. double or reverse draft flue, whereby the smoke, vapor, and heat that usually escapes through the pipes or ues of such tires as are above named are forced up, down, or horizontally, as desired, into a radiator in the room to be warmed and then back to the chimney-flue, from which they were taken, thereby warming the apartment where the radiator is placed without the usual process of cutting holes for pipes through either floors, ceilings,` carpets, or partitions and not subjecting the building to additional hazard by lire; and I do hereby declare th-e following to be a full, clear, and exact description of the same, reference being' had to the accompanying drawings, making' a part of this specification, in which- Figure l, represents a vertical section of a chimney and flues with apartments on two stories also vertical sections of my several improvements combinations and arrangements att-ached. Fig. represents a vertical section of the double horizontal or reverse draft flue with the swinging partit-ion and shackle jointed lever att-ached. Fig. 3, represents a perspective view of the radiator with the double horizontal flue attached at the right hand of the double vertical lines. Fig. et, represents a perspective view of the double vertical section of a reverse draft. flue with the valve, V, at its top.

Similar letters of reference when they oceur in separate figures denote like parts in all the separate sections.

The' arrow heads pointing from figures or letters point to the parts represented by the letters to which they are joined.

The marks prime refer to figures and letters above the floor section, B, B. in Fig. l.

To enable others skilled in the art to construct arrange combine and use my several improvements I will proceed to describe the same having reference to the drawings.

In Fig. l, C, C, represents the vertical section and F, F, F", the flue of a common chimney.

A, A, represent the section of floor on either side of the chimney.

B, B, represent sections of floors in apartments on either side of chimney in the second story.

B, R', represent the radiator in position to warm apartments on either story.

E, represents an open fire in a grate and the arrow points the direction which the smoke and vapors are forced to take when it is desired to warm apart-ments by my combined arrangements V, represents the valve which when drawn forward by rod 8 and 9 cuts oft the directpassage of the smoke vapor and heat to iue F and thereby forces them to pass down the flue D, as the arrow points.

S, S, are the front and back partitions of flue D. which are necessary in combination with valve V, to warm another apartment on the same level with the tire.

N, N represent the swinging partition which when horizontal opens a horizontal draft on its under side, but if placed vertical as shown by the vertical blue lines in Fig. 2, then the iue F would be open direct from N.

The inclined dotted lines converging at L, L, L, show the position of the shackle jointed lever as combined with the swinging partition. L in Fig. 3, fully explains their connection.

H, H', represent a fixed horizontal section of partition in the double horizontal flue K, K.

P, P, represent an inclined or diagonal partition in the radiator, which so divides the radiator as to form two wedged shaped sections of iues thereby throwing the passing heat to the front of the radiator and thence through the small part of the flues sections in the radiator, thus insuring a better radiation of heat.

K, K, K, K, in Fig. l, represent sections of the double horizontal or reverse draft flue which also holds the shackle-jointed levers L, L, which is used by first pulling, then raising and shoving back which motion swings partition N from a horizontal to a vertical position as represented by the dotted lines between Figs. a and 5 and 6 and 7.

Should the fire be in a stove, range, or furnace on the floor A the section of a partition would be required to fill up the aperture cut by the dotted lines l() and 11 having a suitable aperture for the pipes passage.

It may be seen by the foregoing description that the Valve V, and partitions S, N, H, P, so divide the flues and radiator as to form a series of double or reverse draft flues both vertical and horizontal.

I have represented the sections of two radiators in Fig. l, for the purpose of showing how the radiators are to be combined and attached when the fire is on the same level or below the level of the apartment to be heated.

It is plain that the several parts of my improvements can be constructed of various materials and in various forms, therefore I do not wish to limit myself to any particular material or form but to adopt either or any that may be best suited for the purposes herein specified.

Having thus fully described the nature and object of my invention what I claim therein as new and desire to secure by Letters Patent, is-

The construction and use of the horizontal reverse draft flue K, K, with its fixed par.- tition H, its swinging partition N, and jointed lever L, and the two vertical partitions S, S, and their valve V, together with the inclined partition P, as combined with the radiator R, when arranged and combined in the manner and for the purposes specified.
